Higher rank antisymmetric tensor fields in Klebanov-Strassler geometry

TL;DR

This paper investigates higher rank antisymmetric tensor fields within the Klebanov-Strassler geometry, demonstrating that background fluxes suppress their presence, making them effectively invisible in our universe.

Contribution

It provides a string-theoretic analysis showing suppression of massless higher rank antisymmetric tensor fields in a warped geometry, explaining their lack of experimental detection.

Findings

Massless higher rank antisymmetric tensor fields are heavily suppressed.

Background fluxes in Klebanov-Strassler geometry lead to their invisibility.

Supports the non-observation of such fields in experiments.

Abstract

In string theory, higher rank antisymmetric tensor fields appear as massless excitations of closed strings. Till date there is no experimental support in favour of their existence. In a stringy framework, starting from a warped throat-like Klebanov-Strassler geometry, we show that all the massless higher rank antisymmetric tensor fields are heavily suppressed due to the background fluxes leading to their invisibility in our Universe.
